Does this work with Gutenberg blocks or classic editor?

Newsletter Glue works best with Gutenberg. But you will also be able to use it easily with the classic editor.

Does this work with page builders?

Newsletter Glue currently does not work with any page builders. But we plan to do so in the near future. Check back soon!

How will my post look as an email?

Your post will be sent as a simple and clean email. To see it, you can send a test email from inside the WordPress editor before publishing your post. This will let you check your post before sending it to all your subscribers.

Does this just send plain text? What if I want a custom design?

You can customise your newsletter design with the Newsletter Theme Designer. Go to Newsletter Glue > Settings > Newsletter Theme Designer. You can also add custom CSS in the Settings.

The CSS you add here will show up in the emails you send, but not in your blog posts.

To learn more about adding custom CSS to your email newsletter, head here.

What if I don’t want to publish my full post as a newsletter?

You’re not alone. Others use Newsletter Glue as it lets them use the WP editor to write their newsletter.

Simply add a new post, and create your newsletter. Don’t forget to put it in a different category, so that your newsletter will have its own archive.

Why connect to an email service provider (instead of building on inside WordPress?

No need to migrate anything. Don’t touch your existing setup.

  • Email lists, segments, tags
  • Automated email sequences
  • DKIM, SPF records
  • Campaign data

Do you have a subscriber form I can add to my blog?

We have a subscriber form in our pro plugin.

I’m planning to set up a members-only newsletter with restricted content. Will your plugin do that?

Glad you asked! Check out this mega guide we wrote that takes you step-by-step on how you can do that.

Do you have a pro plugin?

Yes! Check it out here.

Works extremely well and really simplifies the workflow for sending newsletters. Can't recommend this plugin highly enough.
January 24, 2021
This is fantastic. I've been looking for a plugin like this forever. It took me less than 2 minutes to install, connect to mailchimp, and send a test email. It could not be easier. The best feature is the ability to go back to old posts and send them as emails to my list. I just did that five minutes after installing. One small thing that's missing is an easy to go back to the initial "connect" screen and watch the video. I powered through the screen and missed it, but I'd like to go back there again.

Sending out newsletters can feel so cumbersome at times. Newsletter Glue has made it so much easier to share our content with our subscribers.

This plugin is hands-down the best plugin I've ever installed and used. I think I was one of the first users. When I encountered a couple of (small) bugs, and had a few feature requests, I reached out to the developers on Twitter. Within less than a day, they responded. And I'm pretty sure we're in significantly different time zones. Usually within another day or two, my wish was fulfilled: bugs fixed, features added. The only word of warning I have is this: make sure you uncheck the "send newsletter" button before clicking an update if you're doing some changes/updates/experimenting with the post. Otherwise, you will (as I did one day) send your newsletter to your entire list three or four times. But, seriously, get this plugin.

Disclaimer: I've been a beta tester for this newsletter for quite some time. I wouldn't recommend NG if it wasn't exactly what I was looking for. I like to have my archive of newsletters on my blog, so it can be discovered through search engines and others can read it as well. This plugin does just that. It makes it easy to write in the WP editor, connect to a ESP and send and publish at the same time. All the smartypants stuff is in the background so I can focus on what is important, delivering value for my readers. This plugin could use some more ESP's to connect to and eventually have your subscriberlist in WordPress. Lesley and Ahmed work hard to get it all done and I think that is fantastic. I can't wait for the premium plugin!

1.1.8, December 16, 2020

New features

  • Strip Newsletter Glue’s default CSS: This is a feature for advanced users who want to completely remove all our CSS from their emails and replace it with their own.


  • In-line CSS: We’ve rebuilt our plugin so that all CSS is inserted inline. There are many advantages, including: we use less code (loads faster, cleaner, less chance of clipping) and forwarded emails retain their styling.
  • Preview email in new tab: Next to “Send test email” you’ll now find a “Preview email” button. This lets you quickly preview emails in your browser, instead of sending a test email every time.
  • Image captions now align bottom center for each image.
  • Campaign Monitor users must select a list ID before sending an email: Blank ID lists now cause an error message and sending is disabled. Previously, we allowed users to send emails without selecting a list. Emails would then get stuck on the backend as Campaign Monitor requires a list in order to send.

Bug fixes

  • Bug fix for Mailchimp audiences: Previously only showed up to 10 audiences. We now show the maximum 1000 audiences.

1.1.7, December 3, 2020

  • New feature: We’ve added a double confirmation when sending updated newsletters. Next to Your email is ready to publish notification, you’ll now see an additional checkbox.

Your workflow when publishing a new newsletter will remain the same. This new checkbox is automatically checked for you, but you can uncheck it.

However, your updating workflow is now improved. This new checkbox is un-checked for posts that are being updated. This solves the problem of saving an updated post and accidentally sending out a newsletter. Only check this box once you’re ready.

  • Bug fix: If a post was previously published then duplicated using the Yoast Duplicate Post plugin, its published status will also show up in the duplicated post. This is now fixed.
  • Bug fix: Link colour chosen in newsletter theme designer not showing up in emails for Mailchimp.
  • Improvement: Remove CPTs that are obviously not for posting content. Like oEmbeds, menus, custom CSS, custom fields, blocks, forms etc…

1.1.6, November 12, 2020

  • New feature: Add preview text to each newsletter. Preview text shows up next to your Subject line in inboxes. It’s a great way to give subscribers a sneak peek of your email and convince them to open it. Find it next to the Subject field in the Send as newsletter section.
  • New feature: You can now choose if you want to add the blog post’s title to the top of each newsletter. Previously, every newsletter automatically added the blog post title. This gives you more flexibility and control over your newsletter’s layout. Find this feature at the bottom of the Newsletter Theme Designer (Newsletter Glue > Settings > Newsletter Theme Designer).
  • New feature: Alignment options (left, center, right) for headers and paragraph text can now be found in the Newsletter Theme Designer. Note this will only show up in your newsletter. It will not affect or appear in your published blog post or in your block editor.

1.1.5, October 29, 2020

  • Improvement: You can now choose to disable Newsletter Glue on selected custom post types. Go to Newsletter Glue > Settings > Additional tab to do this.
  • Minor UI and copy improvements.

1.1.4, October 13, 2020

  • Bug fix: Fixed bug causing our show/hide content blocks to “break” some CSS.

  • Added “Send as newsletter” checkbox on the top toolbar in the post editor. This lets you quickly confirm you’ll be sending a newsletter when you hit the Publish/Update button, and makes it easy to turn off the option.

  • New feature: Added Position header image option, so that you can choose if you want your header image to be above or below the headline.
